I have installed the battery directly and immediately, of course, with iBackupBot among others, tested.
The results were relatively congruent.
negative facts:
- On the label of the battery package was: "NEW" and "1600mAh"
=> Both is not true ...
The "design" capacity is specified with 1420mAh, which is also OK, because the original battery is also listed with 1420mAh. However, the current maximum load capacity was only just under 1200mAh and the battery and had more than 220 charging cycles. Roughly calculated are in daily full charge 3-4 months of use.
If I get a new battery with a label that identifies the component as "new" and it is demonstrably needed, which borders for me to fraud ... almost at the level of mileage tampering with vehicles ...
Next makes disassemble multiple iPhone even better ... Here I would really spend a little more money for an original battery.
